醋酸锌与8-羟基喹啉-5-磺酸(H2QS)以物质的量之比为1:2溶于N,N-二甲基丙烯酰胺(DMF)中,溶液在120℃回流6h,氮气保护。经由配位反应合成了具有反应活性点的小分子8-羟基喹啉-5-磺酸金属配合物(Zn(H2QS)2),该Zn(H2QS)2配合物可引入到聚合物中,得到高分子量的8-羟基喹啉-5-磺酸的发光材料。FTIR确定了Zn(H2QS)2的组成;紫外吸收光谱(UV)、光致发光光谱(PL)说明小分子配合物的发光来自于Zn(H2QS)2基团。
Zinc acetate and 8-hydroxyquinoline-5-sulfonic acid (H2QS) were dissolved in N, N-dimethyl acrylamide (DMF) in a molar ratio of 1: 2. The solution was refluxed for 6h at 120 ° C. protection. A small molecule 8-hydroxyquinoline-5-sulfonic acid metal complex (Zn (H2QS) 2) with a reactive site was synthesized via coordination reaction. The Zn (H2QS) 2 complex can be introduced into the polymer to obtain High molecular weight 8-hydroxyquinoline-5-sulfonic acid luminescent material. The composition of Zn (H2QS) 2 was confirmed by FTIR. UV and PL indicated that the luminescence of Zn (H2QS) 2 was from Zn (H2QS) 2.
